SPECIFICATION forming part of LettersPatent No, 729,577, dated une 2,1903.

To all toll/0121il Til/LyY 05h/Celli?? v induce those already Within theinolosure to pass out of the same. Y

The present invention has for its objects, among others, toprovide animproved form of screen door or Window bymeans of which the flies andother insectsalighting upon the screen, either upon the outsideorinsideof the door or Window, are Vinduced to pass through Openingsin thescreening in a trap included between the Outer and inner faces of thescreen, from which they may be readily removed at anytime desired.

The present constructionembodies in its broadest sense adouble screeninghaving a space therebetween andthe double screening being provided withpassages or openings communicating with the said space and the screenprovidedj with channels or the like leading to said openings andbygwhich thel ies are inducednto pass through such openings into thetrap, from'which latter they cannot escape. One portion of the screen isremovably mounted, so as to provide access to the interior of the trapformed by the two screens. The channels may be disposed vertically,horizontally, or otherwise, their function being the same. The channelsformed in the two screens Varelalternately arranged, so thatthe'openingsin the one channel will be disposed opposite thescreeningintermediate two channelsk on the opposite'side of the door or window.

It is to be understood that. it is not neces- 'sary to 'bait the trapand that the flies may be readily removed therefrom when desired Withoutallowing them to escape into the room.

Other objects and advantages of the invention will be hereinafterdescribed, and the seria No. 118,756. or@ model.)

novel Vfeatures thereof will be particularly pointed out in the appendedclaims.

The invention in its preferred form is clearly illustrated in theaccompanying drawings, which, with the numerals. of; reference markedthereon, form a part of this specification, andin Which-V A Y Figure 1is an elevationv ofna screen-door embodying our invention.

Y

Like numerals of reference indicate like parts in the several views.

Referring now to the details of the drawings, l designates the frame, inFig. l represented as that of a screen-door, and 2 designates theWire-netting, which may be affixed in positionthereon in any suitablemanner. In this instance it is shown as seated in a rabbet 3 in theframe and a Wsecuring-strip eL placed thereover and secured in the.wellknown way; but the manner of securing the wire-netting to the frameis immaterial, and any suitablermeans may be employed. This screenmaterial is formed with a series of channeled, which are substantiallyV-shaped in cross-section, as seen in Fig. 3, and these channelsareprovided at intervals with openings 11,:as shown. These channels mayextend-vertically, as indicated in Figs. l and 2, or horizontally, asseen in Fig. 4or otherwise, as may be deemed mostfexpedient.

7 is a frame, hinged at 8 to one sidejof the frame l, as seen in Figs. 1and 3, and to the outer face of this frame is secured the netting 9,having a series of V-shaped channels 10, which are provided with aseries of openings 6, as seen best in full lines, the openings IOC 11 inthe screening on the stationary frame being indicated by dotted lines inFig. 1. This hinged frame may be provided with suitable means, as hooksl2, for holding it in position upon the frame 1. It will thus be seenthat a space 13 is provided between the screen materials 2 and 9, whichforms a trap into which the flies pass through the openings b' and 11 inthe said screen materials. It will be noted, as seen best from Fig. 3,that the channels 5 and 10 in the two screen materials are alternatelyarranged-that is, the channel of one is disposed opposite the materialbetween the two adjacent channels of the opposite screen material. Thisprovides increased space and dsposes the openings G and 11 out ofalinement with each other. This alternating or zigzag disposition of thechannels is maintained whether the chan nels extend vertically,horizontally, or otherwise.

From the above it will be seen that we provide a simple and cheapconstruction of screen, suitable for door or window, in which a trap isprovided, into which the flies or other insects are led through theopenings in the opposite screen materials and from which space the fliesmay be removed at any desired time by simply moving the screen 7 uponits hinges. It is not necessary to place any bait in the trap, and asthe bottoms of the channels, as well as the tops thereof and the top andbottom of the trap, are closed the fii'es after once entering the samecannot escape.

The construction seen in Fig. 2 is substantially the same as that inFig. 1, except that the frame 7 is of somewhat different construction,and we wish here to state that we do not restrict ourselves to the formor style of the door or of the hinged frame thereto.

In Fig. 4 we have shown the application of the invention to a window, inwhich View 14: designates the frame, 15 the outer screen material, 16the openings, and 17 the openings in the other screen material, theconstruction and mode of operation being essentially the same, exceptthat in this form we make the bottom 18 of the frame movable, hinging itat 19 and providing any suitable means 2O for holding it closed. It willbe readily understood that the opening of this bottom portion disclosesthe bottom of the trap or space between the inner and outer screenmaterials, so that the flies may be readily shaken or otherwise removedtherefrom.

Referring now to Figs. 5, 6, and S, the manner of closing the ends vofthe channels will be readily understood. Referring first to Fig. 6, itwill be seen that the material is slitted by three parallel slits 2l,and when the material is placed in position on the door or window framethe portions 22 and 23 upon opposite sides of the central slit are bentdiagonallyand caused to overlap,as indicated,form ing the triangulardoubled portion 24, which constitutes the bottom of the channel, as seenmore clearly in Fig. 3, and the portions extending beyond thisoverlapped triangular part are engaged beneath the beading-strip orother means which serves to secure it firmly in place.

From the above it will be seen that we have devised a cheap, novel, yetefiicient screen for the purposes described, and while the structuralembodiment of the invention as herein disclosed is what we at thepresent time consider preferable it is evident that the salne is subjectto changes, variations, andl therebetween and communication with saidAspace from both of said surfaces, said screensurfaces being providedwith channels with openings leading through said channels into saidspace and closures for the ends of said channels formed integral withthe screen-surface, substantially as described.

2. A screen for a door or the like comprising a relatively fixed screenwith openings, and a relatively movable screen arranged with a spacebetween them, said screens being provided with channels and openingsleading therefrom communicating with said space said channels beingalternately disposed and having integral closures at the ends.

3. A screen for a door or window comprising a relatively fixed screenwith channels and openings, a relatively movable screen with channelsand openings leading therefrom, and closures at the ends of saidchannels integral with said screens, said screens being arranged at adistance apart with the channels of one arranged opposite the surfaceintermediate the channels of the other and means for closing the ends ofthe space bctween said screens.

4. A screen for a door or the like comprising a relatively fixed screenhaving channels with inclined walls and openings with the ends of saidchannels closed by the material of the screen, a movably-mountedscreen-surface having channels with inclined walls and openings leadingtherefrom with the ends of the channels closed by the screen-surface,the

channels of the one screen alternating with those of the other and themovable section adapted to be moved to provide access to the trap formedbetween said screen-surfaces.
